What is ventilation in firefighting?

Ventilation in firefighting refers to the controlled removal of smoke and heat from a structure. This process is critical during firefighting operations, as it helps to improve visibility, create a safer environment for firefighters, and reduce the risk of flashover—a dangerous and rapid fire spread phenomenon. Effective ventilation allows fresh air to enter the structure, helping to push out the smoke and heat, which can be key to controlling the fire and protecting both occupants and responders.

Proper ventilation techniques may include various methods such as breaking windows or cutting holes in roofs, allowing smoke and hot gases to escape while preventing the fire from spreading through the building uncontrolled. Understanding and implementing effective ventilation strategies is an essential skill for firefighters, as it significantly impacts the overall success of firefighting efforts.
